Preheat the oven to 350℉. Grease and line a loaf pan with parchment paper, set aside.
In a medium mixing bowl, whisk together the flours, baking soda, baking powder, spices, and salt.
Combine all the wet ingredients and sugar in a large mixing bowl. Whisk well.
Pour the dry ingredients into the wet and whisk until no dry clumps of flour remain. Pour the batter into the prepared loaf pan. Bake for 50 minutes or until a toothpick inserted in the top of the loaf comes out clean.
Allow the loaf to cool in the pan for at least 20 minutes before removing it and placing it on a cooling rack to finish the cooling process.
Once the loaf is cooled it can be stored, wrapped well, at room temperature for up to 5 days.
